What does an ion implanter do?
Ion implantation is a low-temperature process by which ions of one element are accelerated into a solid target, thereby changing the physical, chemical, or electrical properties of the target. Ion implantation is used in semiconductor device fabrication and in metal finishing, as well as in materials science research.
What are the advantages of ion implantation technique?
The advantages of ion implantation include the ability to implant virtually any ion species into any substrate with a high level of control of location (lateral and depth) and composition. Ion implantation also has the disadvantages of being a line-of-sight process and requiring high capital cost equipment.
What are the pros and cons of ion implantation vs diffusion?
Ion implantation involves the bombardment of the substrate with ions, accelerating to higher velocities. Advantages: Diffusion creates no damage and batch fabrication is also possible. Ion implantation is a low-temperature process. It allows you to control the precise dose and the depth.
Why high vacuum is required for ion implantation?
Ion implanters must be maintained under high vacuum to permit linear free travel of the ions without occurrence of dispersion due to collisions with ambient gas molecules.
What is the difference between diffusion and ion implantation?
Ion implantation and diffusion are two techniques used in the production of semiconductors with some other materials. The main difference between ion implantation and diffusion is that ion implantation is isotropic and very directional whereas diffusion is isotropic and there is lateral diffusion.
How ions will be generated in the ion implanter?
In the ion implantation process, dopant atoms are first ionized in an ion source. The source typically contains a plasma, generated by either RF or microwave radiation, in which the dopant atoms are ionized by electron impact.
Why annealing is required after ion implantation?
After implantation, a thermal diffusion (annealing) is necessary for the removal of the ion-induced damage, the activation of dopants and the formation of the desired profile shape.
